rails run specific migration

ruby-on-railsmigration

提问by Daniel

I've deleted a table in the database, call it X. db:migrate no longer works. I have a migration file called CreateX. Is there a way to run just that specific migration?

我删除了数据库中的一个表,称之为 X。db:migrate 不再有效。我有一个名为 CreateX 的迁移文件。有没有办法只运行那个特定的迁移?

回答by JP Silvashy

rake db:migrate:redo VERSION=my_version

Or you can go up or down from a specific version:

或者您可以从特定版本上升或下降:

db:migrate:up VERSION=my_version
db:migrate:down VERSION=my_version
